String ID that defines the fill rule for the polygons.
Accepts one of two values:

evenOdd - Algorithm that checks whether a point is located in the fill area by drawing a ray from this point to infinity
in any direction, and counting the number of contour segments in this shape that are crossed by this ray. If the number is odd, the point is inside it; if even, the point is outside it.

nonZero - Algorithm that checks whether a point is located in the fill area by drawing a ray from this point to infinity
in any direction, and checking the points at which a segment of the shape crosses this ray. Starting
from zero, one is added each time a segment crosses the ray from left to right, and one is subtracted each time a segment
crosses the ray from right to left. If the result equals zero, the point
is inside the contour. Otherwise, it is outside it.

Returns coordinates of the two opposite corners of the area that surrounds the geometry.
The first item in the array is the corner with the smallest coordinate values relative to the rest of the points in the area;
the second item is the corner with the largest coordinate values.

Returns the string ID that defines the multipolygon fill rule.
The ID can have one of two values:

evenOdd - Algorithm that checks whether a point is located in the fill area by drawing a ray from this point to infinity
in any direction, and counting the number of contour segments in this shape that are crossed by this ray. If the number is odd, the point is inside it; if even, the point is outside it.

from zero, one is added each time a segment crosses the ray from left to right, and one is subtracted each time a segment
crosses the ray from right to left. If the result equals zero, the point
is inside the contour. Otherwise, it is outside it.
